CRUD de Usuários e Papéis (role weight, permissões, gitignore de worktrees)

- apps/api/src/users/: invite (senha temporária, mesma entropia do
  legado), PATCH (role/isActive, com checagem de peso), reset de senha
  administrativo, troca de senha self-service, grant/revoke de acesso a
  aplicação — cada ação sensível auditada.
- apps/api/src/roles/: CRUD de papéis e gestão de role_permissions,
  exclusivo super_admin (SuperAdminGuard), mirando o requireSuperAdmin do
  legado — deliberadamente não generalizado para o modelo de permissão
  resource+action+scope, por ser a raiz do próprio sistema de
  autorização (documentado em roles.service.ts).
- apps/api/src/auth/role-weight.ts: assertCanAssignRole/assertCanActOnUser
  (eden.md §1.6) — um ator nunca atribui papel nem mexe em usuário com
  peso maior que o seu; super_admin sempre passa.
- .gitignore: .claude/worktrees/ (worktrees temporários de subagentes
  paralelos nunca devem virar submódulo do repo principal).
